The utility model is convenient and easy to replace, and the fixing device of the cutter blade can not loose in use; therefore, the utility model is safe in use.
Description
The utility model relates to a kind of cutting knife, and especially a kind of combined type cutting knife belongs to five metals cutter class and makes the field.
Cutting knife is a kind of cutting tool relatively more commonly used, generally be used for cutting of paper, cloth, plastic or other material, the cutting knife of prior art generally is made up of blade, handle, handle is provided with strip groove longitudinally, blade is installed in the groove of handle, and blade is not held the positioner that a solid blade is set, and perhaps in the handle centre position positioner is set, described positioner generally adopts screw or other similar structures, is used for fixing blade when work.The cutting knife of this structure, simple in structure, but inconvenient operation need be pulled down positioner when especially changing blade, use inconvenient, and dangerous because this positioner is in use, loosening easily and the user is caused danger.
The purpose of this utility model is at the deficiencies in the prior art part, and a kind of combined type cutting knife is provided, compact conformation, reasonable, and blade exchange is convenient, simple, and in use the positioner of blade can not become flexible, thereby uses fool proof.
The utility model is achieved in that it is made up of institutes such as handle of a knife, tool rest, loam cake, locking plates.Handle of a knife and tool rest flexibly connect by center nail, be that tool rest can be that rotate at the center with the center nail, fold in the handle of a knife, the handle of a knife back is provided with clavicle, its role is to control the folding of tool rest when the utility model uses, when promptly having only the hypocleidium of pressing, tool rest just can fold in the handle of a knife, this structure is existing simple technique, is not described in detail here.
Of the present utility modelly be characterised in that the movable loam cake that is provided with above the tool rest, loam cake is polygon, generally is quadrangle, and its shape is corresponding substantially with tool rest.One jiao of loam cake is by the movable edge, tool rest corresponding position that is connected of pin, and loam cake can rotate and can cover tool rest around pin.Tool rest back identical movement formula is provided with a locking plate, and the locking plate cross section is down " recessed " font, and an end is connected above the tool rest back by pin is movable, and tool rest and loam cake can be blocked.Blade is installed between tool rest and the loam cake, and its shape is corresponding with tool rest, and length is longer than tool rest, and stable for blade is installed, blade top has a breach at least, and the tool rest correspondence has the projection corresponding with breach, blocks blade.The loam cake drift angle is provided with a recess, and corresponding position, locking plate the inside is provided with protruding position, and when locking plate was pressed, protruding position embedded the recess place of loam cake, and blade, tool rest and locking plate are linked into an integrated entity, and blade can not become flexible.Locking plate is not held and also is provided with a handle, pulls handle, can be easy to open locking plate, draws back loam cake again, thus desirable bottom knife, and operation is easily.
For blade and tool rest are adjacent to, can some grooves be set on surface, tool rest the inside, to reduce blade and tool rest contact area.Certainly, can and groove needn't be set blade be contacted steadily with tool rest by blade and tool rest surface both level of processing is smooth.In the utility model, the blade two ends mouth that can put the first edge on a knife or a pair of scissors, thus blade can be used conversely.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation, and accompanying drawing also makes an abstract.
Fig. 2 is Figure 1A-A cutaway view.
Fig. 3 is the utility model assembled state schematic diagram.
Among the figure, the 1st, handle of a knife, the 2nd, clavicle, the 3rd, cutter holder, the 4th, center nail, the 5th, blade, the 6th, loam cake, the 7th, locking plate, the 8th, protruding position, the 9th, handle, the 10th, recess, the 11st, tool rest, the 12nd, breach, the 13rd, projection.
Referring to Fig. 1, the utility model is made up of institutes such as handle of a knife 1, tool rest 11, loam cake 6 and locking plates 7.Handle of a knife 1 flexibly connects by center nail 4 with tool rest 11, be that tool rest 1 can be that rotate at the center with center nail 4, fold into 1 li on handle of a knife, handle of a knife 1 back is provided with clavicle 2, its role is to control the folding of tool rest 11 when the utility model uses, when promptly having only the hypocleidium 2 of pressing, tool rest 11 just can fold into 1 li on handle of a knife, this structure is existing simple technique, is not described in detail here.For easy to carry, 1 arbitrary on handle of a knife also is provided with a cutter holder 3.
Referring to Fig. 3, the tool rest 11 top movable loam cakes 6 that are provided with that are characterised in that of the present utility model, loam cake 6 is polygon, generally is quadrangle, is quadrangle in the present embodiment, and its shape is corresponding substantially with tool rest 11.6 one jiaos of loam cakes are by the movable edge, tool rest 11 corresponding position that is connected of pin, and loam cake 6 can rotate and can cover tool rest 11 around pin.Tool rest 11 back identical movement formulas are provided with a locking plate 7, and locking plate 7 cross sections are down " recessed " font, and an end is connected on tool rest 11 backs by pin is movable, and tool rest 11 and loam cake 6 can be blocked.Blade 5 is installed between tool rest 11 and the loam cake 6, and its shape is corresponding with tool rest, and length is longer than tool rest 11, and promptly blade 5 cutting edges should expose tool rest 11 outsides, and can fold into 1 li on handle of a knife in the lump together with tool rest 11 etc.Stable for blade 5 is installed, blade 5 tops have a breach 12 at least, and tool rest 11 correspondences have the projection 13 corresponding with breach 12, and its quantity is all corresponding with breach 12 with the position, blocks blade 5.Loam cake 6 drift angle places are provided with a recess 10, and corresponding position, locking plate 7 the inside is provided with protruding position 8, and when locking plate 6 was pressed, protruding position 8 embedded recess 10 places of loam cake 6, and blade 5, tool rest 11 and locking plate 7 are linked into an integrated entity, and blade 5 can not become flexible.Locking plate 7 is not held and also is provided with a handle 9, pulls handle 9, can be easy to open locking plate 7, draws back loam cake 6 again, thus 7 replacings of desirable bottom knife, and operation is easily.
For blade 5 and tool rest 11 are adjacent to, can some grooves be set on surface, tool rest 5 the inside, to reduce blade 5 and tool rest 11 contacts area, certainly, can be smooth by surface both is processed, and groove needn't be set blade 5 is contacted steadily with tool rest 11.In the utility model, the blade 5 two ends mouth that can put the first edge on a knife or a pair of scissors, thus blade can be used conversely.
Compact conformation of the present utility model, reasonable, blade exchange is convenient, simple, and in use the fixture of blade can not become flexible, thereby uses fool proof reliable.
